Various fluid filtration devices are in widespread use. Some examples of fluid filtration devices include filtration devices used in connection with engines or vehicles, such as engine oil or transmission fluid filtration devices, for example. Many standard transmission filtration devices are configured to include a housing with an inlet and an outlet, and the housing may have a relatively flat and thin profile for attachment to a transmission oil pan. Transmission fluid often flows into these filtration devices from an inlet on the flat side of the bottom and out of an outlet on the top surface. The housing is usually divided into an upper half and a lower half, which are joined to each other by pressure welding or welding. One side of the housing can be both plastic, or one or both can be metal.
このようなタイプのろ過装置の一例は、単層平坦シート部材ろ過装置である。ここでは

An example of such a type of filtration device is a single layer flat sheet member filtration device. Here, the flat sheet of filter media spreads across the housing and is held at the edge of the housing, for example, located close to the two housing attachments. Another type of such a filtration device is a so-called bag filtration device. Here, one filter medium is folded back so that the entire unperiphered peripheries are sealed together, thus forming a substantially closed bag,
A hole is provided that forms an opening leading into the bag. The opening is usually connected to the inlet by sealing against the inlet. In such a bag filtration device, the fluid flows directly into the bag from the inlet of the housing, passes through the bag member, reaches the outside of the bag, and then flows out from the outlet of the housing.

The flat sheet or bag member can be of a very low density filtration type, for example a metal or plastic screen or a low density knitting, or, for example, a medium or very high density fabric or felt It may extend to a higher density type such as a type.

These filtration devices have been found to be very suitable for use, for example, in vehicle transmissions, to filter vehicle transmission fluids. But,
A compromise is often imposed on the density of the filter media. For example, fluids or oils are usually more viscous or concentrated in cold starting conditions and then become less viscous or concentrated as the transmission is raised to its stable operating temperature. In the case of components suitable for filtration at higher operating temperatures, the density is so high that fluids can be disturbed or blocked to undesired levels during cold start operations. On the other hand, in the case of a low-density member that can secure a necessary flow rate as well as a certain degree of filterability during start-up operation, there is a possibility that filtration with favorable accuracy cannot be performed at any temperature.
この問題を解決するのに使用された１つの方法は、低温始動期間において高密度なろ過
材を部分的又は全体的に回避するある種のバイパスの試みである。しかし、新しくかつ改
良されたろ過配置が常に望まれている。
One method used to solve this problem is a type of bypass attempt that partially or totally avoids dense filter media during cold start-up periods. However, new and improved filtration arrangements are always desired.

The high-density sheet member 22 includes an opening 24 penetrating therethrough. As a matter of course,
Depending on the operating state, a part of the fluid flows into the inlet 26 and passes through the high-density sheet member 22 and then flows out of the outlet 28 as it is. However, some fluid can also pass through the opening 24. As described above, the fluid flow from the inlet 26 to the outlet 28 finally passes through either the high-density sheet member 22 or the opening 24.

The spacer 30 is provided as shown and includes an inner ring 32. A folded bag-like low-density bag member 40 is also provided. The low-density bag member 40 is configured by first folding a flat sheet as shown in FIG. 2 in the direction of arrow A in FIG.
The non-folded peripheral edge is sealed to form a substantially rectangular bag. The openings 42 in FIG. 2 are provided through the low-density bag member 40. The ring 32 of the spacer 30 is sealed against the opening 24 of the high-density sheet member 22, and is also sealed against the opening 42 of the low-density bag member 40. Accordingly, a part of the fluid flowing into the inlet 26 can pass through the opening 24, the ring 32, and the opening 42 in order to reach the low-density bag member 40. The fluid that flows into the low-density bag member 40 passes through the low-density bag member 40 while being filtered, and can flow out from the outlet 26 after reaching the outside of the low-density bag member 40. .

The lower half 14 includes dimples 50 that separate the high-density sheet member 22 from the bottom of the lower half 14. Further, the spacer 30 may be provided with a further dimple 36. The dimple 36, together with the dimples 52 in the upper half 16, keeps the low density bag member 40 open and also keeps it away from the inner surface of the upper half 16. Bag member 4
Additional ribs 38 can be provided on the spacer 30 to separate the zero from the dense sheet member 22. Further, in order to separate the low-density bag member 40 from the upper half 16, an additional rib 54 may be provided so as to protrude inward from the upper half 16.

Referring now to FIG. 4, the general flow in the normal state passing through the filtration device 10 is indicated by arrows that schematically illustrate the flow state. For example, the fluid flows through the inlet 24 and a portion of the fluid flows smoothly into the low density bag member 40. This fluid is a low-density bag member 4
Flows out from zero and thus coarsely filtered, can pass through at least one of the ribs 54 or 32 and flows out of the outlet 28. Some remaining fluid passes through the dense sheet member 22, mixes with the fluid filtered by the low density bag member 40, and exits 2
Eight from the same. The spacer 30 facilitates this.

Of course, this arrangement provides at least some degree of bypass arrangement,
As a result, the fluid has a tendency not to pass through the high-density sheet member 22 while it is in a highly viscous and low-temperature flow state, and instead is guided to pass through the low-density bag member 40. The low density bag member 40 has a relatively large surface area due to its bag shape, and therefore
A large amount of viscous fluid can be accommodated. As the temperature rises, the ratio of the fluid that passes through the high-density sheet member 22 tends to increase.

Thus, the embodiment shown in FIG. 4 provides a two-layer member arrangement in which a relatively flat, single-layer, high-density member is provided in combination with a bag-like, relatively low-density member. The fluid flows predominantly in parallel and passes through one of the members, and with the exception of some small amount of fluid, the fluid tends not to pass through both members in succession.

Some embodiments of the present invention can be arranged in essentially the same manner as shown in FIG. 4 except for the aspect in which the high density and low density of the members are reversed. That is, the bag can be a high-density member while the single-layer flat sheet is a low-density member.

FIG. 5 shows a second embodiment of the present invention. The filtration device 110 includes a housing 112. The housing 112 is very similar to the housing 12 according to the first embodiment, except that the inlet 126 extends upwardly into the housing 112 and is directly connected to a pair of bag members to be described in more detail. Similar. For example, a first bag 122 having a denser member with an opening 124 sealed to the inlet 126 is provided. The bag 122 is then completely surrounded by a lower density member bag 140 having an opening 142, and the opening 142 is also sealed to the inlet 126. Thus, opening 1
Both 24 and 142 are sealed to each other and to the inlet 126. The dense bag 122 also has an exit hole. Thus, some fluid can pass continuously through the bags 122, 140 while some fluid can pass through the outlet holes,
As a result, it is filtered only by the outer lower density bag 140. Thus, the filtration device 110 allows a combination of serial and parallel flow. FIG. 5 also shows a schematic flow arrow to show the internal flow path.
